| > Does each airline have their own way of exporting this data? Is there a single entity that aggregates from all of them? I work with a lot of smaller airlines, and from my experience I can tell you no. Many of them can't even tell you their actual route list or flight schedule or pricing logic. They typically buy a booking engine solution from just a few major players (Sabre, Amadeus, TravelPort) who do have centralized data, but access to them is slow, expensive (at scale) and restrictive. I've been told by one of the GDS's that our use case doesn't apply for direct GDS access, and we have to go through the airlines' access method. I don't know if these booking engine solutions include access to an API or not, however most airlines have said either they don't have an available API, or don't know how to share access to one. Some of the larger airlines do seem to have their stuff together. But we're just starting to work with them, and because of all the bureaucracy involved it will likely be months before anything happens. The screen scraping method djhworld mentions is a worthwhile approach if you'd personally like to track a few routes. I've done the same to watch prices to NYC (I visit friends often) on a few of the low-cost airlines. It's nice because you can tailor the logic to your preferences. Such as don't bother searching flights that don't include a weekend in the trip; or set my alert threshold 25% higher when the trip involves a holiday or long weekend. |
